And if you are using a swinging link tank and open-wire line, they can't
measure anything.

And, they aren't going to bother unless you are unquestionably over the
limit. Chances are that the guy has been causing interference or they
would not be there. . I heard about one guy who was cited for running
23k out from a 4CX15,000A/8281. This guy was a champeen turkey. He ran
the 8281 most every night on 80m. He lived in a housing tract with close
spaced houses. . He reportedly caused widespread interference to
electronic equipment in the neighborhood. The FCC inspector who visited
Mr. Turkey lived in the neighborhood and was reportedly experiencing
interference to his stereo equipment.
